APPLYING SIMPLEX LATTICE IN OPTIMIZING SELF-COMPACTION CONCRETE COMPRESSIVE STRENGTH

Due to its convenience, speed, and quality of implementation, overusing of self consolidating concrete necessitates adopting new methods to optimize its designs. This study focuses on effective parameters in determining the decision variables related to the objective function of optimization concrete and introduces a set of optimization techniques; finally, based on the simplex method, the study presents the highly optimized mixing amounts of each self-consolidating concrete component such as cement, water, coarse and fine aggregates, superplasticizer, and powder, according to the strength standards. The results demonstrate that the optimization method selection depends on the objective function, decision variables, and constraints and has a significant impact on the calculation of concrete mix design. Besides, the component''s value parameter poses a large influence on the compressive strength of concrete.
